You can do such things as set up to be informed when an excel cell changes. God knows why you'd do it in PowerPro, but it's probably easy to do if I'm doing threading anyway. > Is it reasonable to regard requests and connection setups > > as taking no time, or should they be threaded: i.e. are you happy > > that PowerPro wil block for the duration of the DDE transaction, or do > > you need to launch transaction and be informed wiehn if finished by > > callback? > This is a hard one.

Doing both probably relatively easy: in fact, the way DDE is built (if you want a response the DDE mech calls a callback) lends itself to use of PowerPro callbacks. But of course now that I've dug into things a bit, it's all a bit more complex than I knew before (e.g. DDE uses clipboard formats to specify what kind of data is being moved, so that means a datatype parameter for request/poke services....and so on). Upshot, might be a month or so, as my annual skiing trip is coming up shortly. Attention: PowerPro's Web site has moved: http://www.ppro.org Yahoo!
